A boost driver is coupled to the sense node. A second switch and the connection node are coupled in series. The boost driver outputs a first voltage when the first, second, third, fourth switches are turned on. The third switch is then turned off and the boost driver outputs a second voltage higher than the first voltage such that the voltage level at the sense node is not higher than a system voltage. The third switch is turned on, then turned off and the boost driver outputs an intermediate voltage between the first voltage and the second voltage. A state of the memory cell is determined during output of the intermediate voltage.
